There are already tons of resources out there with the same kinds of activities you can find in the books, so here are some ideas for very alternative kinds of supplemental activities to make this lesson more fun and exciting. These are activities, games, songs, skit ideas, project ideas, ways of presenting material, videos, etc, that I have compiled over 15 years of teaching. There's a blend of simple quick little communicative activities and bigger activities that are the kind that have you excited to teach even while you're driving to school.
